TROLLEY SWITCH.

Application filed January 12, 1922. Serial No. 528,792.

To all whom t may concern:

Be it known that I, Anciano ZIMMERMAN, a citizen of the United States, residing at Ansted, in the county of Fayette and State of `West Virginia, have invented a new and useful Trolley Switch, of which the following is a specification.

This invention relates to trolley switches, the primary object of the invention being to provide novel means for cutting out a section of a trolley to permit repairs to be made with facility.

Another object of the invention is to provide means for securing a trolley Wire to the body portion of the switch to insure against the trolley wire becoming disconnected therefrom.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing:

Figure 1 is a sidey elevational view of a switch member constructed in accordance with the present invention.

Figure 2 is a plan view thereof.

Figure 3 is a sectional view taken on line 3-3 of Figure l.

Figure 4 is a sectional detail view through one of the insulating bells.

Referring to the drawing in detail, the device embodies opposed members 5 and 6, each of which being formed of conduct-ive material and provided with a bore extending along the lower portion thereof to accommodate the sections of the trolley wire asson ciated with the switch.

Set screws indicated at 7 extend through suitable threaded openings formed in each of the sections, the inner extremities of the set screws contacting with the trolley section associated therewith, the trolley sections being indicated at 8,

The sections 5 and 6 are disposed in spaced relation with each other, the section 5 being formed with a slotted portion to receive one end of the knife switch 9, a pivot pin 10 being provided to pivotally support the knife switch 9. Carried by the opposed section 6, is a switch member 11 which embodies opposed jaws between which the free end of the knife switch moves to contact therewith, and complete a circuit through the sections of the switch proper.

An insulating block 12 is secured to the knife switch 9, as by means of rivets 13 which pass through registering openings in the block and knife switch 9, a portion of the block l2 being formed into a handle 14 to be gripped by a person manipulating the switch to throw the same into and out of operation.

Suitable insulating members such as indicated at 15 may be connected to the respective sections 5 and 6, in any suitable and well known manner, the insulating members being also connected with the supporting bar 16, which is shown as supported above the insulating members 15.

It is contemplated to use switch members as described, adjacent to the trolley wire leads and to this end, an opening 17 is formed in one of the sections of the switch member, which opening accommodates the lead wire 18, securing screw 19 being provided to secure lead wire 18 against movement with respect to the switch member.

From the foregoing it will-be seen that if it is desired to repair a section of a trolley wire, it is only necessary to move the switch 9 out of contact with the switch member 11, breaking the circuit between the switch members and leaving that section of the trolley wire dead.

Having thus described the invention, what is claimed as new is A switch member for connecting the ends of trolley wires, comprising opposed wire clamping sections, a supporting bar, insulating members having connection with the wire clamping sections and having connection with the supporting bar to connect and support the wire clamping sections, a pivoted switch member supported by one of the wire clamping sections, a contact mem-r ber supported by the opposed Wire clamping section and adapted to cooperate with the pivoted switch member to complete the circuit between the Wire clamping sections, and a block in circuit with the switch member and adapted to move to a position between the adjacent ends of the clamping sections.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of t-Wo Witnesses.

ALONZO ZIM`MERMAN.
